" enlarged bore. Portions 37 7 thereof substantially as is shown in Fig-- The opposite ends of the cylinder 26 are connected by pipe assemblies 32 and 32 to ports 33 and 33' respectively which are formed in a valve body 34 bolted, as at 35, to an arm 36 offset inwardly from the supporting bracket 27 at the outer end of the cylinder 26. These ports 33and 33' open outwardly of the oppositevertical sides of a valve body 34 and are angled interiorly thereof in a forward direction where they open into a passageway-37extending horizontally through the valve body in a plane parallel to that of the cylinder 26.

A sliding valve 38 is mounted in the passageway 37 and has portions 39 and 39 the opposite endsof the passageway through and 37 and through packing glands 40 screw threaded intothe latter. The valve 38 is of elongated form and has enl'argements 38 and 38" at its opposite ends, which move to centered position with movements of the valve38 as will be hereinafter more fully explained.

Opening into the front side of the valve body 34 and into the passageway 37, at a point substantially mid-way between the ports33 and 33is an air or water inlet 41, while an outlet 42 leads outwardly of the same side of the valve body but from the enlargement 37 r of the passageway 37. ,An exhaust port 43 extends through the outer part of the valve body 34 inparallel relation to the passageway 37 therein and connects the enlarged bore portions 37 f and 37 in order to exhaust the air or water from the inlet side of, the valve body. to the outlet side ure 5.

The free end of the valvestem or rod 39 is pivotally connected, as at 44, to one end of a'pair of oppositely disposedlinks 45 which have their outer ends pivoted, as at 46, to a roller 46 engaged in an arcuate slot 47 formed in anactuating arm 48; the latter being pivoted, as at 49. at an intermediate point, below the slot 47, to an offset portion 10 formed at the upper end of the adjacent of the vertical supports or legslO.

The lower end of the arm 48, in turn, is

pivoted as at 50, to ablock 51-mounted on the free end portion of a pitman or rod 52 between a pair of spacer sleeves which have their outer ends abuttedagainst collars 52 secured to the pitman or rod 52 by means of'pins'52. Formed on the arm 48,

below the slot 47, is a second arcuate slot 53 into which a stop member or pin 54 projects from its point. of securement in the bracket arm 36, in order to limit the opposite swinglng movements of the arm 48 and consequently the length of travel of the valve 30 in the passageway 37 of the valve body 34.

oppositely directed stem projecting outwardly of respect tothe ports 33'and 33" corresponding with the reverse directional The other or inner end of the pitman or rod 52 is secured in the lower end of an arm' ing action of the pitman or rod 52, the upper end thereof is formed to provide an extend- .ed'portion 48' 'on which a weight 55 is adjustably secure the like 56'. l 1 p In the operation of the a'pparatus, as thus constructed and over the felt bed or table a of a paper felting machine, the inlet pipe 41 will be connected to a suitable source of water or air supply and the outlet pipe 42 to a waste drain or the like, while a flexible hose con'-. nection 57 will lead to the side 'outlet'16 of by means of a set screw or the T-coupling 16 from a hot water supply for the distribution ofthe waterlto the spray nozzles'24.

With the sliding valve 38 in the position as shown in Figure 5 and the sprayerheadstructure and the piston rod 18 at the left. hand end of the frame 11, pressure from the inlet 41 will pass to the inletport 33, through the passageway 37 and from thence by way of the pipe'assembly 32 to the left hand end of the cylinder 26, when the pisto'nin the latter will be movedwith the rod 18-toward the rod. During the finalmovement of the piston and rodassembly 18 in, this right hand direction, the shoulder 58, at the: outer-connected angled end of the pipe extension 21 will be forced against the, arm 53 which will then move therewith during the remain.

der of its travel. r This movement of the arm 53 is transmitted by the pitman or rod 52 to the pivot block 51 and pivot 50, when the arm 48 will be swung on the pivot49 to aleft hand position, the weight 55 acting to acc'eleratesuch movement after the arm passes the vertical center of its arc of travel. a I

This movement of the arm 48 is transmitted to the valve 38 by the links 45lwhenj the valve takes position in the passageway37 of the valve 36 to establishcommunication between the inlet 41 and the port Here, water or air will pass the passageway 37 from the inlet 41 and will pass into, the port 33 to and through thepipe assembly 32to the arranged, and positioned vlot] V sageway 37, from hence, it will pass through the exhaust port 43 and outwardly of the outlet 42.

As soon as the sprayer head assembly has nearly traversed the frame 11 in the left hand direction of its travel, the shoulder 58 at the outer angled end of the pipe extension 15 strikes the arm 53 and moves the same with it to the limit of its travel, when the pitman or rod 52 will cause the arm 48 to again swing on its pivot but in a right hand direction to bring the valve 38 back to its first position as aforesaid.

By this arrangement, the sprayer head with the nozzles 24 will be passed over the paper machine felt at a very slow speed to effect a thorough washing off or cleaning of the felt stock in a desired manner. By providing two spray nozzles 34 as shown due allowance is made for full coverage of the felt.

Without further description, it is thought that the features and advantages of the invention will be readily apparent to those skilled in the art, and it will of course be understood that changes in the form, proportion and minor details of construction may be restored to, without departing from the spirt of the invention or its scope as claimed.
